# QJump over NIC queue

Moving high priority packets to the front of the network interface card (aka ```queue jumping```).

The idea of this project comes from a paper called

[__Queues Don’t Matter When You Can JUMP Them!__](https://www.usenix.org/conference/nsdi15/technical-sessions/presentation/grosvenor) that

its focus is on deployable approach to controlling network interference in datacenter networks.

Our goal is to create a kernel module to perform this approach on our local system's __NIC__. In this repository

we present this module's code-base. In the next sections we are going to describe this module by presenting 4

steps that its taking.

## project steps

### step one (NIC event capturing)

The first step is to capture packets that are inserted into NIC queues. We should capture both

input packets and output packets.

### step two (event management)

Next step is creating a event callback function to be called whenever we capture a packet. This callback

function gets packet data and decides where it belongs to.

### step three (queue reordering)

After callback function is called, we need to reorder our system's NIC queue.

### step four (system logging)

In the final step we log these events into a file for debugging and tracing.
